Verifiable check weights

We stock 19 check weight ranges that can be supplied verified, with 439 versions in total from 0.001 g to 2 tonnes. From Kern.

Why this version

If you charge by weight, the instrument must be verified. These versions can carry the green M mark and are supplied verified from the factory.

Maintenance, calibration and repair

We calibrate and adjust test weights in our own laboratory, Masslab, in OIML classes E2 to M3; the certificates are then available in the Masslab customer portal. See calibration with a certificate and what a calibration certificate contains.

Frequently asked questions

Which class of test weight suits my scale?

One class finer than what the scale reads. For an analytical balance that is E2 or F1, for a bench scale F2 or M1, for a floor scale M1 or M2.

Can you also calibrate test weights?

Yes. We calibrate weights and supply a certificate stating the measurement uncertainty.
